I separated the earlier message-length checks so that you get "invalid
invalid authentication request" or "received invalid protocol
negotiation message", depending on whether it was an 'R' or 'v' message.
With that, "invalid invalid authentication request" becomes translatable
anyway, which makes the point on translation overhead moot. I added a
comment to mention that it's unreachable, though.
I also reformatted the comments a little more.
Pushed with those changes, thanks!
